We thank you for your understanding. How can planes navigate in fog? How can a GPS (global positioning system) receiver determine its position (and why is it sometimes considerably off the mark)? Radio waves penetrate fog and clouds and have mostly obsoleted the lighthouses of old. In this workshop, we use ultrasonic waves as a model for radio waves. Students use ultrasonic receivers and an oscilloscope to determine their position in the lab using direction (angulation) and time (lateration) measurements.Objectives:Waves; interpretation of oscilloscope waveforms, wave motion; use of oscilloscope, geometry and measurement.Delivery Type Hands On WorkshopLevel S2, S3, S4, S5, JC1, JC2Number of Pax 10 to 20Duration 2 hoursTiming Fees $15 How to book 2019 programmesFor instructions on how to book our programmes, please read our School Programme online booking guideTo book a programme, please access the online booking system
